A stack machine's compact code naturally fits more instructions in cache, and therefore could achieve better cache efficiency, reducing memory costs or permitting faster memory systems for a given cost. In addition, most stack-machine instructions are very simple, made from only one opcode field or one operand field.
A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the ...

Separate from the stack definition of a MISC architecture, is the MISC architecture being defined by the number of instructions supported. Typically a minimal instruction set computer is viewed as having 32 or fewer instructions, [1] [2] [3] where NOP, RESET, and CPUID type instructions are usually not counted by consensus due to their fundamental nature.
Newer processors contain a dedicated stack engine to optimize stack operations. Pentium M was the first x86 processor to introduce a stack engine. In its implementation, the stack pointer is split among two registers: ESP O , which is a 32-bit register, and ESP d , an 8-bit delta value that is updated directly by stack operations.
Stack machine, an architecture centered around a pushdown stack; Protocol stack, a particular software implementation of a computer networking protocol suite; Solution stack, a group of software systems, increasing in abstraction from bottom to top; Stack-based memory allocation, a memory allocation scheme based on the principle of "last in ...
Some machines use a stack for arithmetic and logical operations; operands are pushed onto the stack, and arithmetic and logical operations act on the top one or more items on the stack, popping them off the stack and pushing the result onto the stack. Machines that function in this fashion are called stack machines. A number of mainframes and ...
The ZPU is a microprocessor stack machine designed by Norwegian company Zylin AS to run supervisory code in electronic systems that include a field-programmable gate array (FPGA). [1] The ZPU is a relatively recent stack machine with a small economic niche, and it has a growing number of users and implementations.
